    摘要： Provided is a method of producing an aluminum structure using a porous resin molded body having a three-dimensional network structure, with which it is possible to form an aluminum structure having a low oxide content in the surface of aluminum (i.e., having an oxide film with a small thickness), and in particular, it is possible to obtain an aluminum porous body that has a large area. The method includes a step of preparing an aluminum-coated resin molded body in which an aluminum layer is formed, directly or with another layer therebetween, on a surface of a resin molded body composed of urethane, and a step of decomposing the resin molded body by bringing the aluminum-coated resin molded body into contact with concentrated nitric acid with a concentration of 62% or more.

    摘要： The present invention provides a mold for fine electroforming M having a simple structure. In order to improve the productivity of a metal product, an electrode portion can be arranged with a much higher density, and a metal thin film formed on the electrode portion can easily be peeled off. The present invention provides a manufacturing method for manufacturing the mold M with a higher accuracy and by an easier way.The mold for fine electroforming M has a conductive substrate 1 to function as a cathode during electroforming and insulation layer 2 having an opening 21, which has a shape corresponding to a shape of a plane shape of the metal product P and is through to the conductive substrate 1, and composed of an inorganic insulation material having a thickness T2 of not less than 10 nm and less than one-half the thickness T1 of the metal product P. The surface of the conductive substrate 1 exposed at the opening 21 is adapted to serve as the electrode portion.The manufacturing method of the mold M has steps of: forming an inorganic thin film 2′ to grow into the insulation layer 2 in an area excluding an area, where resist film R is pattern-formed, on the surface of the conductive substrate 1; and removing the resist film R to form the opening 21.

    摘要： A cold-cathode fluorescent lamp having high brightness with long life and an electrode for this lamp are offered. The electrode comprises a base and a covering layer that covers the surface of the base. The base is formed of one metal selected from nickel, a nickel alloy, iron, and an iron alloy. Consequently, a base having a shape, such as a cup, can be easily produced. The covering layer comprises (a) a surface layer made of tungsten or molybdenum and (b) a bonding layer that is made of zinc alloy and that is placed between the base and the surface layer. In comparison with nickel and iron, tungsten and molybdenum are resistant to sputtering, have a small work function, and have a high melting point. The presence of the bonding layer enables sufficient bonding between the surface layer and base. A cold-cathode fluorescent lamp provided with the foregoing electrode can suppress the reduction in brightness and the consumption of the electrode. Therefore, it has high brightness and long life.
